HOUSTON — A giant laboratory aboard
the International Space Station (ISS) will get a bit bigger today when
astronauts add an attic to the already tour bus-sized Japanese module.
Wielding the space station's robotic
arm, astronauts will pluck a storage closet from a temporary perch and attach
it to a more permanent home on the roof of Japan's $1
billion Kibo laboratory module.
"It's a pretty simple move," space
station flight director Annette Hasbrook said late
Thursday here at NASA's Johnson Space Center. "The crew will control all of
it."
Discovery shuttle astronaut Karen
Nyberg - the chief robotic arm wrangler for NASA's
STS-124 mission - will lead the Kibo module move,
with Japanese astronaut Akihiko Hoshide and station
flight engineer Greg Chamitoff watching over the
docking rings between the two orbital rooms.
The move is slated to begin at about
2:57 p.m. EDT (1857 GMT) today, with Nyberg hoisting the storage closet - also
known as the Japanese Logistics Module (JLP) - from the top of the station's
hub-like Harmony node and moving
it about 30 feet (10 meters) to the rooftop of Kibo.
The actual move is expected to take less than an hour once vestibules between
the rooms are prepared, NASA officials said.
"We're looking forward to [Friday],
and then the following day, for the JLP relocation and the robotics system's
initial checks," Tetsuro Yokoyama, deputy Kibo operations project manager, told reporters Thursday.
Kibo's storage room was delivered
last March during an earlier shuttle mission to await the arrival of its parent
module, the Japanese Pressurized Module, which Hoshide
and his STS-124 crewmates installed earlier this week.
The squat storage module weighs
about 18,490 pounds (8,387 kg), is about 14.4 feet (4.4 meters) wide and 13
feet (4 meters) long. But it is dwarfed by the larger research module, a
massive 32,000-pound (14,514-kg) orbital room that is about 37 feet (11 meters) long
and includes two windows, a small airlock and a 33-foot (10-meter) main
robotic arm.
A porch-like external platform and a
second, smaller robot arm to handle external experiments are slated to round
out the Kibo facility when they launch aboard a NASA
shuttle next year.
To prepare for today's module move,
the joint 10-astronaut crew of Discovery and the station removed eight phone
booth-sized equipment racks from the storage room and installed them inside
the main Kibo lab on Thursday. Two spacewalkers
also cleared the lab's roof-mounted docking port to receive the smaller module
that day and installed new cameras to aid use of Kibo's
robotic arm.
"The JLP needs to be completely
empty," Hoshide said of today's move in a NASA
interview. "The plan is not to have any racks inside because we're trying not
to freeze [them] just in case a heater failed and we can't have the module
warmed up."
In addition to moving the storage
room, shuttle commander Mark Kelly and station commander Sergei Volkov are expected to discuss their joint mission with
reporters on Earth today.
NASA's Mission Control here at the
Johnson Space Center roused Discovery's crew Friday with the song "Bright as
Yellow" by the band Innocence Mission, a tune chosen especially for Nyberg, who
is making her first spaceflight and is the 50th woman ever to fly in space.
"Good morning Discovery, and a
special good morning to you today Karen," NASA astronaut Shannon Lucid radioed
up to the shuttle.
"Good morning Shannon and everybody
in Houston," replied Nyberg, who will be the first
person to wield three different robotic arms in orbit during her mission. "Thank
you so much for waking us up with that music."
